IMPROVEMENT IN CULTIYATORS.

Specification forming part of Letters Patent No. 183,090, dated October10, 1876; application filed April 17, 1876.

To all whom it may concern:

Be it known that I, EDWARD WIARD, of Louisville, in the county ofJefferson and State of Kentucky, have invented a new and usefullmproveme-ntin the Iron-Beam Double-Shovel Plow; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure l is a perspective View of my improvedplow. Fig. 2 is a perspective view of one of the bracket-braces by whichthe plows are connected to the beam. Figs. 3. 4, and 5 are views of oneof the shovels and the standard thereof, showing the way of connectingthe former to the latter.

The nature of my invention consists in a singleiron-beamdouble-shovelplow, havingits shovels arranged on opposite sides of thebeam, one in rear of the other, and sustained by peculiar braced andstayed brackets in such manthe shovels are confined to the beam may bereadily passed and secured. It consists, third, in the lever-actingbracket, constructed with a loop, to receive the beam edgewise, and witha horizontal passage through its looped portion, to permit the insertionof a wooden pin through the looped portion and the beam.

In the accompanying drawings, A is a single wrought-iron or other metalbeam for a double-shovel plow. This beam is in form of a broad, narrowbar, and has a suitable clevishook, a, formed on, or attached to, itsfront end. B B are the handles, attached to the beam at a point which isforward of its rear end about one-third the length of the beam. 0 G aretwo braces, extending down, respectively, from about the middle of thelength of the handles to the end of the beam, and converging toward oneanother until they touch the beam, where they are fastened together andto the beam by a single bolt, 1;. D D are shovel plows or bladesattached to curved standards E E. The lower ends of the standards arelooped, as at c, and through these looped portions screw-bolts d, withcountersunk heads, are passed, said bolts being first inserted throughthe holes in the shovels. On the ends of the bolts d flangedclamping-bars fare placed, and behind these bars are nuts 9. The barsextend across the back of the looped ends of the standards and bindagainst the sides of the same, and, when the nuts are screwed up, theykeep the shovel steady against any movement on either side of itscenter. By loosening the nuts the shovels can be raised or lowered forplowing shallow or deep. The standards, with the shovels attached, arearranged upon opposite sides of the beam, one in rear of the handles,and the other forward of the same. The connecting devices between theshovels and the beam consist of the lever-brackets F F, made ofmalleable cast-iron, or other metal, and formed with a loop, h, toreceive the beam edgewise, and a wooden relief-pin, h, which is passedhorizontally through the loop and beam, and with an abutting-plate, i,for bearing against the side of the beam, a tubular stay, j, for a longfastening screw-bolt, k, to pass through, a flanged plate, I, forreceiving the upper end of the shovel-standard, and a curved diagonalbrace, m, for staying the plates against the lateral thrust or straincaused by the labor of plowing performed by the shovels. The bolt k isformed with a head on one end, and screw on the other, on which latter anut, n, is applied. Said bolt is passed horizontally through theshovel-standard, tubular stay and plates of the bracket-brace, and thebeam, and receives the nut n on its screw end, and the said wooden pinpasses through the loop and beam, all as shown in the drawings.

I do not claim, broadly, as my invention wooden relief-pins applied toagricultural implements; but

What I do claim, and desire to secure by Letters Patent, is-

1. The combination, in the double-shovel plow. of the single iron-beam,the two shovels, with an open loop, to receive the plow-beam and thebraced and stayed brackets, all conedgewise, and with a passage throughits structed and arranged as and for the purpose looped por ion, topermit the insertion through set forth. 1 it and the beam of a woodenpin, substantially 2. The plow-shovel bracket F, constructed asdescribed. with the abutting side plate, the tubular stay, EDWARD WIARD.flanged plate, and diagonal brace, in the man- Witnesses: ner and forthe purpose described. HENRY H. MODOUGALL,

3. The leverbracket, as described, made ALFRED AVERY.
